I have a doubt on Adding Custom filed in SQ02 Query

[Sugayagan]

Hi Gurus,

I created A Query in SQ02 ,I need to Link the Table VBRP and  /IDT/D_TAX_DATA.

So what I link VBRP-VBELN and /IDT/D_TAX_DATA-DOCUMENT and then when i try to Link VBRP-POSNER With /IDT/D_TAX_DATA Document Line Number Both have different  DATAELEMENT LENGHT .

so i Decided to create Additional filed in SQ02  with Name POSNER With Numeric 6 Length,

My question is How to Link VBRP POSNER And Additional Filed POSNER To get the DATA IN /IDT/D_TAX_DATA.

NOTE: After adding Additional filed During Table Link could not find custom filed. SAP BTP ABAP environment SAP Community
