很多顾问在使用Arun时候很疑惑，既然Arun在后台配置有预留的出口，为什么没有示例以及Help说明呢？要知道出口很重要的一点，是需要告知用户交互的接口内容。
其实在NOTES上，SAP为大家做了很多说明。特整理如下：
Symptom
A user wants to create a user exit in the ARun, however, the interface is not known.
Other terms
ARun, allocation run, user exit
Reason and Prerequisites
As a prerequisite, you must implement Note 520450.In order to prevent that customer-specific user exits are overwritten through an upgrade or the import of a FixPak, you must create the functionmodules in the customer namespace.This note is constantly updated, make sure that you always use the latest version.
Solution
In the following, the interfaces of the individual user exits are described:
1. User exits in the allocation run: (Customizing path: AFS allocation run - User exits - Define and activate user exits) a) User exit before the requirements filter Application: 11 - Filter: processing prior to filtering This user exit is _executed before the application of the requirements filter. Table parameter: - im_bedf LIKE j_3abedf_s - im_arve LIKE j_3aarve_s Exceptions: - error_message b) User exit after the requirements filter Application: 7 - Check: After the first check (for example, cancellation date) This user exit is _executed after the application of the requirements filter. Table parameter: - im_bedf LIKE j_3abedf_s - im_arve LIKE j_3aarve_s Exceptions: - error_message c) User exit after the selection Application: 10 - Selection: Processing after selection This user exit is _executed upon completion of the selection of the requirements and of the stocks. Table parameter: - im_bedf LIKE j_3abedf_s - im_best LIKE j_3abest_s - im_arve LIKE j_3aarve_s Exceptions: - error_message d) User exit for the determination of customer-specific release rules Application: 5 - Release: Release rule determination This user exit is _executed before grouping/sorting. Table parameter: - im_bedf LIKE j_3abedf_s Exceptions: - error_message e) User exit before sorting for filling the customer-specific sort fields Application: 4 - Sorting: Additional fields This user exit is _executed before sorting the requirements. Table parameter: - im_bedf LIKE j_3abedf_s Exceptions: - error_message f) User exit for filling the customer-specific grouping fields Application: 1 - Grouping: Additional fields This user exit is _executed before grouping. Table parameter: - im_bedf LIKE j_3abedf_s Exceptions: - error_message g) User exit for converting the group numbers Application: 3 - Grouping: Renaming group number This user exit is _executed after the specification of the group numbers. Table parameter: - im_bedf LIKE j_3abedf_s Exceptions: - error_message h) User exit before the allocation Application: 12 - Allocation: Processing before the allocation This user exit is _executed before the allocation, namely per group or order in each case. Table parameter: - im_bedf LIKE j_3abedf_s - im_best LIKE j_3abest_s Exceptions: - error_message i) User exit before the list display (allocation results) Application: 19 - Result: Processing before list display This user exit is _executed before the list display of the allocation results. Table parameter: - ch_bedf LIKE j_3abedf_s - ch_bdbs LIKE j_3abdbs_s Exceptions: - error_message j) User exit before the update Application: 9 - Posting: Processing before posting This user exit is _executed before the _updateof the allocation results.

User exits in the allocation run during the release check: (Customizing path: AFS allocation run - User exits - User exits in the release check) Here, different levels are available for the user at which a customer-specific release check can be carried out. If you set export parameter ex_exit to 'X' in a user exit, the standard release check will NOT be _executed at this level; if this parameter remains ' ', the standard check is _executed after the user exit in addition a) Group Import parameter: - im_groui LIKE j_3abedf_s-groui - im_relpa LIKE j_3arepa - im_recf LIKE j_3arecf Export parameter: - ex_action LIKE j_3arepa_s-orful_g - ex_exit LIKE j_3abdbs_s-mark Table parameter: - im_bdbs LIKE j_3abdbs_s - im_best LIKE j_3abest_s Exceptions: - others b) Header Import parameter: - im_aufnr LIKE j_3abdbs_s-aufnr - im_relpa LIKE j_3arepa - im_recf LIKE j_3arecf - im_relcheck LIKE j_3aarco_s-release_check Export parameter: - ex_action LIKE j_3arepa_s-orful_g - ex_exit LIKE j_3abdbs_s-mark Table parameter: - im_bdbs LIKE j_3abdbs_s - im_bdbs_r LIKE j_3abdbs_s - im_best LIKE j_3abest_s Exceptions: - others c) Line group Import parameter: - im_aufnr LIKE j_3abdbs_s-aufnr - im_lngr LIKE j_3abedf_s-j_3alngr - im_relpa LIKE j_3arepa - im_recf LIKE j_3arecf Export parameter: - ex_action LIKE j_3arepa_s-orful_g - ex_exit LIKE j_3abdbs_s-mark Table parameter: - im_bdbs LIKE j_3abdbs_s - im_best LIKE j_3abest_s Exceptions: - others d) Delivery group Import parameter: - im_aufnr LIKE j_3abdbs_s-aufnr - im_grkor LIKE j_3abedf_s-grkor - im_relpa LIKE j_3arepa - im_recf LIKE j_3arecf Export parameter: - ex_action LIKE j_3arepa_s-orful_g - ex_exit LIKE j_3abdbs_s-mark Table parameter: - im_bdbs LIKE j_3abdbs_s - im_best LIKE j_3abest_s Exceptions: - others e) Item Import parameter: - im_aufnr LIKE j_3abdbs_s-aufnr - im_posnr LIKE j_3abdbs_s-posnr - im_relpa LIKE j_3arepa - im_recf LIKE j_3arecf Export parameter: - ex_action LIKE j_3arepa_s-orful_g - ex_exit LIKE j_3abdbs_s-mark Table parameter: - im_bdbs LIKE j_3abdbs_s - im_best LIKE j_3abest_s Exceptions: - others f) Schedule line Import parameter: - im_bedf LIKE j_3abedf_s - im_relpa LIKE j_3arepa - im_recf LIKE j_3arecf Export parameter: - ex_action LIKE j_3arepa_s-orful_g - ex_exit LIKE j_3abdbs_s-mark - ex_zmeng LIKE j_3aactn-zmeng Table parameter: - im_bdbs LIKE j_3abdbs_s - im_best LIKE j_3abest_s Exceptions: - others g) Schedule line VAS Import parameter: - im_bedf LIKE j_3abedf_s - im_vare LIKE j_3avare - im_recf LIKE j_3arecf Export parameter: - ex_action LIKE j_3arepa_s-orful_g - ex_exit LIKE j_3abdbs_s-mark - ex_zmeng LIKE j_3aactn-zmeng Exceptions: - others h) VAS Import parameter: - im_bedf LIKE j_3abedf_s - im_vare LIKE j_3avare - im_recf LIKE j_3arecf Export parameter: - ex_action LIKE j_3arepa_s-orful_g - ex_exit LIKE j_3abdbs_s-mark - ex_zmeng LIKE j_3aactn-zmeng Table parameter: - im_bdbs LIKE j_3abdbs_s - im_best LIKE j_3abest_s Exceptions: - others i) BOM Import parameter: - im_aufnr LIKE j_3abdbs_s-aufnr - im_grkor LIKE j_3abdbs_s-grkor - im_bore LIKE j_3abore - im_relpa LIKE j_3arepa - im_recf LIKE j_3arecf Export parameter: - ex_action LIKE j_3arepa_s-orful_g - ex_exit LIKE j_3abdbs_s-mark Table parameter: - im_bdbs LIKE j_3abdbs_s - im_best LIKE j_3abest_s Exceptions: - others j) Final check Import parameter: - im_relpa LIKE j_3arepa - im_recf LIKE j_3arecf Export parameter: - ex_action LIKE j_3arepa_s-orful_g Table parameter: - im_best LIKE j_3abest_s - im_bedf LIKE j_3abedf_s - im_bdbs LIKE j_3abdbs_s - im_bdbs_r LIKE j_3abdbs_s Exceptions: - others 3.
