ABAP Questionnaire for Upgrading from 4.6c to ECC6

[Former Member]

Hi gurus,

I'm an ABAP developer and I'll have a project soon that will focus on the upgrade of a customers SAP system from 4.6c to ECC5. I just want to ask if you can give me a questionnaire or a guide taht will focus on the ABAP side of the upgrade. This is my first time that I will be involved in an upgrade project.

Thank you very much,

Andre

The upgrade isn't difficult at all

In ABAP you must change all the functions of files like WS_DOWNLOAD .You must use GUI_DOWNLOAD or CL_GUI_FRONTEND_SERVICESS class.

The inherited classes need that their constructor call the constructor of the father class.

In HR you have to be carefully with the casting of infotypes.

The files of the application server need encoding .The default encoding is unicode but you can deactivate using encoding non-unicode.

The syntax is more restricted.

You have a new and very good editor .A new debugger too.

Be carefully with indexes when access a field structure or similars.

In XML you must use encoding utf-8

Hi Andre,

The adjustment of Repository objects is carried out with transaction SPAU. Only those objects that have been modified by you and are being redelivered by SAP in an upgrade are presented for adjustment.
