customs export declaration screen fields - form mapping

[#1]

Friends,

I have to map data from customs export declaration document to a print form.

I am new to using GUID keys and do not know how to use them while selecting data from tables.

Further, I am not sure how to link the screen fields in the customs export declaration to table fields in the GTS system as i have to display data in the form based on the value in screen fields in the customs document.

Points will be rewarded for helpful answers.

John,

I do not see the structure IS_PRN-H_TXT in my system.

Anyhow, to read the data from table types ,you can refer to my earlier post(I pasted it below).

For the table types H_PAR, I_GEN etc...

read the table H_PAR into a workarea(WA_H_PAR) of TYPE /SAPSLL/PRN_H_PAR_S and move data.

Partner number variable = WA_H_PAR-PARNO.

Thanks

RK,

Please check again. IS_PRN has a component H_TXT ( which is for Customs Document Header:Texts).

If not , do you know any component where the header texts might be stored.
