BEx Variable Input Help (F4) Maximum Number of Rows

Hi Experts,

We using Bex 3.x version. Now, the user is asking to change the maximum number of rows (by default 500, for my case) to 1000. (While executing the workbook, on the variable pop-up screen where we can search for input help (F4) values). For surely, there is some global setting needs to be corrected but not sure. I have checked in T-code: SPRO and some of the threads but not get the apt solution.

Could you please share us your inputs/experiences as how can we increase maximum number of rows in the input help.

Many thanks in advance!!!

Best Regards

Venkat...
