BDC use problem

Former Member — Fri, 09 Apr 2021 03:32:05 GMT

Hi exports！

I use BDC for the Inspection characteristics of the Routing(Tcode：CA02),

there will be error messages "The characteristic number is too large"(QP311).

But when I use the CA02 to manually enter the same value, I have no error message.

What causes it to use BDC to cause the line QP311 error message？

What value do you see in debug? What field is it? What value do you see in the screen when you run in 'A' mode?

Hi sandra.rossi,

Thank for your respond！

I use the debug mode to confirm the program LQPAAFI5 (the program that generates message QP311), the parameter z_tabix is not the same in the BDC mode and manual input.

This program(LQPAAFI5) will compare whether the characteristic number size exceeds the default value, but the characteristic number default value in the BDC mode is 002,but in manual input mode, the characteristic number default value is 020 (this is the correct value).

In addition, the reason for z_tabix is different. I think it may be caused by the value of sy-stepl, and the sy-stepl is different because of using BDC mode?
