B1form xml error Data source alias already exists

Hi experts

Here is my pbm :

I 've a SQL UF which displays a kind of action list for a kind of worflow.

If i launch this UF , displays data ,close SAP and then open SAP and launch again the UF,   i have an error msg coming

Its comes before the complete opening of the SQL UF form.

I've noticed that the pbm does not show up if i run SAP as an Admin : my guess is that there is somewhere a file or a folder which cannot be modified or overwritten if i ve not enough rights

Can you tell me where is this file or folder ?

Best regards
