Restrictions 
The following restrictions apply to the use of Adobe LiveCycle Designer for form processing in an SAP system:
A generated form should not exceed the following number of pages:
On Microsoft Windows servers: approx. 1000 pages
On Unix or Linux servers: approx. 2000 pages
You can create form layouts for right-to-left languages. However, if you switch to one of these languages (for example Hebrew, Arabic), an automatic adaptation of the layout is not supported.
The PDF forms called locally from Web Dynpro applications by Adobe Reader or Adobe Acrobat may be saved as temporary files on the hard disk of the PC. This may result in a data protection issue.
