I have got a Internal Table Node LT_ITEM in the interface, which has amount field (WRBTR) and Indicator SHKZG field. In the Adobe Form I have to change the value of WRBTR to positive or negative based on the value in SHKZG. But I will not be showing SHKZG in the output so it will not bound in the layout of the form and will not be in Hierararchy. How can I read the SHKZG field for each row and change the WRBTR value. If SHKZG is bound in the table I will be able to read directly but as it is not bound it is only available in the context.
