Hello,
strange behavior...
In our system, using POWL for Vendor Lists, if i click onto "Display" or "Edit" from action buttons (or if i click onto the hyper-link from Vendor List number), method WDDOMODIFYVIEW from V_ASL_DOTC_SOS view (WDC /SAPSRM/WDC_DOTC_ASL_SU_D) is triggered...
But whatever...
I do not understand you logic.
Just do an overwrite Exit and manage on your own value ITM_RELEASED: during the LOOP to transfer CLL data to PDO data, line 155, after the move corresponding:
MOVE-CORRESPONDING ls_cll_item TO ls_pdo_item. " map ui-structure to pdo-structure
unset ls_pdo_item-itm_released.
Before row is modified, field will be set, but after row creation/modification, PDO layer will updated.
Regards.
Laurent.
