problem in data source mapping - CAF entity service.

Hi,

I created an external service for the bapi given below.

It has 2 tables as input parameters.

In entity service I created attributes(for input parameters) for table1 and table2. but in data source i couldn't map more than one attribute to the MATNRSELECTION and PLANTSELECTION.The attributes of the bapi are under the same collection.

I'm using NWDS version 7.0.06.

BAPI_MATERIAL_GETLIST (To List all Materials for a Particular Plant)

Input Parameters:

Table1: MATNRSELECTION

MATNRSELECTION-SIGN

MATNRSELECTION-OPTION

MATNRSELECTION-MATNR_LOW

Table 2: PLANTSELECTION

PLANTSELECTION-SIGN

PLANTSELECTION-OPTION

PLANTSELECTION-PLANT_LOW
