如何阻止指定类型的SAP CRM附件被上传到服务器 crmerpsapSAP云平台SAP Cloud Platform

Requirement: end user could not be allowed to upload attachment whose size is greater than a given limit for example 400KB. Solution: (1) Create a BAdI implementation via SPRO->Customer Relationship Management->Basic Functions->Content Management->Business Add-Ins-> Confirmation of Changed Documents

 

 

(2) copy the following source code to BAdI Implementation. For code detail please refer to comment for each line.

ABAP METHOD if_ex_crm_documents~carry_out_action. CONSTANTS: cv_max_size TYPE int4 VALUE 409600. "400KB DATA: lt_loios TYPE skwf_ios, ls_error TYPE skwf_error, lv_size TYPE sdok_fsize, lt_badios TYPE skwf_ioerrs. READ TABLE changed_documents ASSIGNING FIELD-SYMBOL(<first_line>) INDEX 1. CHECK sy-subrc = 0. " The badi implementation will be called whenever there is change on attachment ( create, update and delete), since it is necessary to filter out the change " mode CHECK <first_line>-action = 'CREATE_DOCUMENT'. DATA(ls_bo) = VALUE sibflporb( instid = <first_line>-instidbor typeid = <first_line>-typeidbor catid = <first_line>-catidbor ). DATA(ls_loios) = VALUE skwf_io( objtype = <first_line>-objtype class = <first_line>-class objid = <first_line>-objid ). APPEND ls_loios TO lt_loios. CALL METHOD cl_crm_documents=>get_file_info EXPORTING loio = ls_loios IMPORTING file_size = lv_size. CHECK lv_size >= cv_max_size. " Since this BAdI implementation could only be called after the attachment is created, so technically speaking we could not prevent the attachment creation indeed, but could only delete the attachment after its creation CALL METHOD cl_crm_documents=>delete EXPORTING business_object = ls_bo ios = lt_loios IMPORTING bad_ios = lt_badios error = ls_error. COMMIT WORK AND WAIT. " raise an error message to prompt user to upload the attachment with smaller size lo_service->add_message( EXPORTING iv_msg_type = 'E' iv_msg_id = 'ZCM_JERRY_TEST' iv_msg_number = '000' ). ENDMETHOD.

Activate the BAdI implementation:

 

 

Now if an attachment is uploaded which exceeds 400KB, the end user will see an error message in UI.
