Hi experts,
Let’s say i have 3 Tables. I want to compare and change the information contained in Table1 regarding the information contained in both Table 2 and Table 3.
The information that interests me is 1 , and 0 only if no value 1 was found for a material. Example:
Table 1:
MATERIAL | VALUE |
AAA | 0 |
BBB | 0 |
CCC | 0 |
Table 2:
MATERIAL | VALUE |
AAA | 1 |
BBB | 0 |
CCC | 0 |
Table :
MATERIAL | VALUE |
AAA | 0 |
BBB | 1 |
CCC | 0 |
What I expect is that Table 1 will be as following:
MATERIAL | VALUE |
AAA | 1 (from Table1) |
BBB | 1 (from Table3) |
CCC | 0 |
My BW tables will contain many thousands of data, i am afraid about performance issues.
Do I have to use imbricated loops, or it’s better to use read tables?
Thanks for your support.
Amine
