Field Unknown error message in program node

[Former Member]

I'm brand new to SAP and trying to get to grips with Smartforms. This is a very basic question I'm afraid but hope someone will answer it.

I'm trying to perform the following in a program node

SELECT SINGLE * FROM MARC INTO WA_MARC

WHERE IT_VBDPA-MATNR = MARC-MATNR.

IT_VBDPA is defined in TABLES tab of Form Interface

WA_MARC is defined in Global Definitions

IT_VBDPA is defined as an input parameter on the program node

WA_MARC is defined as an output parameter.

I get 'Field IT_VBDPA-MATNR unknown' error message. What am I doing wrong?

you forgot to declare it_vbdpa in the interface of your coding node.

I did define IT_VBDPA in the input parameters section of the program node. Is that what you mean by interface of coding node?
