me21n change line item dropdown list value

[Former Member]

hi experts,

i have a requirement to automatically remove the aulty po line item when user click on CHECK or SAVE button, i done this by removing the record from ETT[] and POT[] at ENHANCEMENT-POINT mm06ef0p_pruefen_01 SPOTS es_mm06ef0p_pruefen INCLUDE BOUND.

it is working fine except one scenario which is, if the faulty line item is 00020, and the line item dropdown list is selected line item 20, after i removed the record from POT[], it hits abap runtime error. when i check at debugger, it is caused by system will look for line item 00020 ( follow dropdown list value ) but the record is removed, so come to error... it is working fine if the dropdown list is selected line item 10.

so i am looking for a way to change the dropdown list value.

or you all have some other suggestion?

please help... i need it urgently coz i have been solving the problem for 2 weeks....

thanks a lot

Hi,

generally it's not a good idea to delete item without using standard method. You can see one example why it is usually complicated. Maybe I have a workaround for you. You can try to use BADI ME_PROCESS_PO_CUST. There is a method CHECK where you get reference to PO header. You can easily get references to your items by calling method GET_ITEMS. So you will perform your check for each item and for wrong items you will call method INVALIDATE. This item will be marked as invalid and it will not be posted. Here I do not know how it will be displayed to user. Maybe the user will have to delete this item manually.

Cheers
