Suitecrm - Printing issues on pdf template (quote module)

Suitecrm version: 7.10.7 Dears, I need a suitecrm expert to solve 2 urgent issues. Please find below some explanations + check uploaded files. Thx for you interest. Best regards. Issue 1 We have created custom product line items in the quote module. I currently have several pdf models connected to this module. One of them must print according to certain rules: - Name of the pdf model: "Fiche métrage_test2" - As is: In each group created in a quote can be several products / services. When I print as pdf, each custom line items fields are printed for each product lines in a group. Moreover when service line does not exist in a group, the variable name $aos_services_quotes_name is also printed on the pdf document. - To be (requirements) For each group, custom line items has to be printed ONLY FOR THE FIRST PRODUCT. For the others in a same group, custom line items must not show (see doc in attachment). If variable $aos_services_quotes_name does not exist in a quote, it must not be printed on the pdf. Issue 2 We have created a custom calculated field in the quote module called {prix_c}. - Name of the pdf model: "[login to view URL] OK" - As is: When printing as pdf, this custum fields appears as 0,00. If an admin user updates the quote then the correct value appears on the pdf document. If a normal user (not admin) updates the quote, {prix_c} still appears as 0,00 on the pdf document. - To be (requirements) solve the problem so that the correct value is always reproduced on the pdf document.
