Custom field passing to R3 backend from ISA Ecommerce
We are on R3 4.6C with Java 6.40, ISA ecommerce.
I have a custom field plant displayed on order.jsp for each line item.
Now I want to send this plant corresponding to each line item to the backend. There i want to do a custom ATP check with this plant. If there is no availability i want to through an error for that line item on the order.jsp.
I am not able to find any BADI's and i dont know which FM is been called from front end, when i click TO ORDER button in the order.jsp.
Could anybody give me some suggestion/solutions on this please.
I appreciate it and thanks in advance.
do you know the possibility of replacing a standard function module?
I would wrap the standard function module with a custom function module. The custom function module should call the standard function module first and after calling the standard fm you can do your ATP check. The standard function module contains a table for customer extensions. you could use the extension table for passing additional data to the r/3 system.
