ERP SALES ORDER problem

Hi Gurus,

I'm facing a problem with the ERP SALES ORDER, when I try to create a sales order in CRM in Spanish Language appears a Pop-up Empty to "select" a sales transaction, but when I logon in English to CRM UI, and I try to create the ERP Sales Order the Pop Up no appears automatically, in this case appears the screen to capture the sales order, and the system does not performed any pop up to select the available sales orders.

Spanish Logon:

Pop-up to select a sales transaction (empty)

English Logon:

Screen to capture the sales order without Pop-up.

I already checked the customizing but everything looks OK.

Is there any problem with the language? or maybe I missing some customizing step?

Do you have idea what is the problem?

Thank you so much for your help.

Maricarmen.
