Extend data source field length

Question

Hallo experts,
I wonder, what are the influences in BW if a R/3 data source field length changes.
Example: size of VBAP customer field ZZ_TEXTis changed from 40 to 80 chars. Data are extracted via 2LIS_11_VAITM datasource.
1) After replication of new datasource, what happens, if the infosource is not updated to the new size, is the field just truncated? Is the next delta load working or is an init load necessary?
2) If fieldsize is updated in infosource and infoproviders too, what happens to the delta management?
Thanks for your ideas!

Ans : First of all I dont understand why you need to load text as transactional data.You could have mainitained a infoobject for customer and could have maintained text for it.This would have made your job simple.
If above is not your case and if text is transaction data then ya if you dont update the infoobject with correct length it will be truncated.
If its from now on the text is changed then you can change it now but I think it wont allow it to change as long as you delete it where ever its used.Hence you will need to reload.
2) If fieldsize is updated in infosource and infoproviders too, what happens to the delta management?
Ans : You may have to reload.
Hope this helps.
