Get the START DATE of /SAPAPO/RRP3 in APO
I am using the Transaction /SAPAPO/RRP3.
Based on the Purchase order number and Line item number of ECC i need to get the START DATE of the order in APO.
E.g : PO NUMBER = 4500002213
ITEM NUM = 000010
Now i have a table /sapapo/posmapn which returns me the POSID based on the PO NUM and ITEM NUM.
My requirement is to get the START DATE of that order.
I tried to use the FM /SAPAPO/OM_ORDER_GET_DATA but it returned me a SY-SUBRC = 3.
Can anyone suggest me how do i get the START DATE for that ORDER in APO.
