Functionality
The function module is used to check the release status of the purchaseorders selected. The indicator FRGKZ is set. If you do not explicitlyset the optional import parameter i_opcode, the entries will only bechanged. If you do set the parameter, entries will be deleted dependingon their release status.
The function module is also used to check whether follow-on documentsexist for purchase orders that have already been released. If they doexist, the indicator HISTKZ is set. If you are only interested in therelease status of the purchase orders, you can avoid this option byexplicitly setting the optional parameter I_SEL_REL = 1.
If one of these two indicators has been set, this is noted in theError_Status as a warning and is logged accordingly in theE_ERROR_MESSAGES error table.

Notes
IMPORTANT: The internal table CHANGING_HEADER must be sorted bydocument number. No document number must appear more than once in thetable.
If it exists, the optional table I_EKKO must also be sorted correctly.
