In most situations, an extraction in BI fails due to an invalid value for the InfoObject. For example, I failed to load 0MATERIAL_ATTR because some of the material number is like "[2Q235-A100060D" (note the '[' character) while '[' is an invalid character for BI by default.
Check OSS note #173241 – “Allowed characters in the BW System&rdquo to review (same as the picture below)
If you can't change the material number, we quite simply have to include whatever is causing problems as a permitted character in BI.
Step1:
Run TCODE RSKC
Input '[' and execute the program. This will add '[' to the allowed characters list.
Many documents has mentioned parameter 'ALL_CAPITAL'. It is powerful but also a little bit dangerous I think. So here I added only the must-have one.
After this, the extraction should work properly.
Step2:
Since I was loading 0MATERIAL, you can figure that this is a brand new BI system. So if you've been running for some time, step 1 is not enough. Now we encountered another error:
If we open the cube which has 0MATERIAL to check the cube content (or open InfoObject 0MATERIAL) the following error message occured:
Run TCODE OMSL (or SPRO > IMG button > BW > General settings > Set Material Number Display) both in R/3 and BI, because we need to ensure the settings in BI is the same to that in R/3.
Hope the above could help you out on the invalid character issue.
