Cannot extract the embedded font arial.Some char might not be displayed

Question

Hi Folks,
              Our requirement is to generate the customer account statement for a set of cusomters during a particular period.
                     we  use a script to generate the statement and convert it to pdf.This pdf is then stored in the application server and retrived using cg3y transaction.The transaction allows the statement to be generated for multiple customers and company code.
the problem that we face is that the first customer account statement is generated properly the rest of the statements are not displayed properly.When we open the customer account statement we get the error 'Cannot extract the embedded font arial.Some characters might not be displayed properly'.All the Headings that we of the font BOLD ARIAL were not displayed.
This error does not occur for the first pdf file generated.(say we have 3 customers  for the 1st customer pdf is proper however for the next two error'.
                     When I checked the application server I found that the first file has font subtype as Type1 and then rest of the files have font subtype as Truetype.
This is working fine.I downloaded the file to pc using cg3y.the pdf looks fine.

I have to change the tont subtype to Type1 as in my first cust. statement.Is there a way to this???????
There can be no problem with the code cause the account statement generated for first customer is perfect.
Any suggestions will be appreciated.

Hi,
this can be related to the compression of the PDF file.
You can turn off the FlateDecode compression again via report RSTXPDF3 as described in Note #843480. It is a little confusing. The option 'FLATE_COMPR_OFF' needs to be set to 'On' to turn off the FlateDecode compression.
To set this please run as follows:
se38 -> RSTXPDF3 -> enter 'FLATE_COMPR_OFF' in the 'Name' field -> Select 'Change Settings' radio button
You will get a pop-up 'Do not use flat compression'.
Select the 'on' button.
After this check if the PDF is created correctly.
regards,
Aidan
