Hello Justin,
It would be much easier If you use a Z driver program. But know issue, you can also achieve your requirement by using java script. Do as below:
1. Suppose you internal table "Item_table" (On body page) has below fields:
ITEM_TABLE
VBELN
POSNR
MATNR
WERKS
LGORT
2. GV_ALGORT is a text field on master page.
3. in script, path for ITEM_TABLE-LGORT would be like below:
xfa.record.IT_TABLE.DATA[*].LGORT
4. Now, Select GV_LGORT text field on master page.
5. Go and select "Ready:Layout" event, "JavaSceipt" as language and "Client" as Run At.
6. Write below code (you can change path like mentioned in point 3 if item_table is nested in other
structure or internal table ):
var v_lgort = xfa.resolveNode("xfa.record.IT_TABLE.DATA[*].LGORT").value;
this.rawValue = v_lgort;
Note: If above is not working.then select above code and delete, press save button. And write same code under "Form:ready" event.
I hope it will solve your problem. Reward point if it solve your problem.
