Dear Hari,
If the activity type of the confirmation has set the flags as
mentioned (indicator MANIST in table COKL is set) the system will simply
NOT post any quantity on the sender cost center/activity type during
the confirmation.
So all quantities which are currently missing (as these were not
updated by the confirmation) must be posted with transaction KB51N.
If you implement the coding corrections of #760437 you have the
possibility to change the message BK263 from "I" to "A" in transaction -
which is however not recommended.
So the advised procedure is:
-post all mising quantities with transaction KB51N first
-then run the report ZRKMANIST_RESET to remove the flag MANIST (which is
the reason why the confirmations did not post quantities on the
sender cost centers)
After this procedure, the quantities will again be updated when you
post confirmations.
Best regards,
Jason
