Hello Venu

To find out the type of an parameter simply double-click on its "Associated Type". IMPORTING and EXPORTING parameters may be either fields, structures or table types. TABLES parameters are always tables.

- POHEADER = structure

- POITEM = table (because TABLES parameter)

- POSCHEDULE = table (because TABLES parameter)

Now what is the meaning of these "X" parameters like POITEMX? POITEMX is also a table (because TABLES parameters). In field PO_ITEM you have to enter the Item Number of Purchasing Document. All others fields simply define which corresponding field in TABLES parameter POITEM should be updated ('X' = update; ' ' = do nothing).

Example:

- In POITEM you have 10 entries with PO_ITEM = 1 - 10.

- For PO_ITEM = '2' you want to change its short text (field SHORT_TEXT)

Then you have to fill the following fields:

- in POITEM (itab) the entry with PO_ITEM = '2' has in field SHORT_TEXT = <new short text>

- in POITEMX (itab) you add an entry with PO_ITEM = '2' and SHORT_TEXT = 'X'

The logic is the same for IMPORTING parameters POHEADER and POHEADERX. You will find this logic in many BAPIs.
