Thank you, but I fixed it using user parameter 'JEA' + transaction variants (SHD0) for each transaction we need.
Now when we enter another transaction and load a document with another branch not corresponding to the user, and then we enter trx FB60 for example, this last and erroneous branch is loaded again. For the moment, only solution I know is logout and logon to load correct branch. I tried transactions for cleaning buffers, with no success.
Can any tell me if it is possible to limit/correct that value before be loaded with the last value showed, if it is incorrect for the user ?
Thank you and regards
