Access Tables Via RFC

Access Tables Via RFC

If you are trying to read some information from SAP and you can't find the right BAPI then RFC_READ_TABLE can do the job for you.

RFC_READ_TABLE is powerful RFC it gives you the access to all tables and views in SAP. I basically used RFC_READ_TABLE for Material Master Search application on the Intranet.

Now you may say there are lots of BAPI for this functionality. You are right but I had to work around the BAPI to get Prices (Moving Average Price) and it just did not work very well. Because of the nature of the application I had to use RFC_READ_TABLE because then I can use powerful SQL expression for searching. RFC_READ_TABLE give you the ability to code the where clause which is quite enough.

I have included part of the code use in asp page to read ENT1027 for Mgroup and M description & number but without object creation. The other part of the code reads MBEW for price & quantity.
