We are Migrating the Material master data to Legacy, so we don't want Master data in SAP. While generating PO we mean that Material should not considered in SAP and only short text for the PO given importance simply PO without material Master.
Po posting is done from legacy using an Customized Interface Program.In the Input file we will be getting an Extra field(material Description) along with Material Number.This Material number and Material Description should be concatenated into the field ---Short Text(EKPO-TXZ01).
The material number and the short text should be separated by a special character.This Material number will be the unique key for the validation of material number,while doing GR posting from legacy to SAP.
We need to create a Interface Program so that the GR is created in legacy and posted in SAP,While posting of GR from Legacy we are considering 101 and 102 Movement Types for MB01 transaction ,We are opting for BDC , which one is advisable (BDC or any BAPI).
any inputs will be highly appreciated!!
