Using WWI Compression

[Former Member]

Hi @all,

we are thinking about minimizing the amount of data by using the WWI compression.

As we have no experiences with this - does anybody can give us a guideline what needs to be customized and how we can check, whether the compression is working? And whether we need a certain release level (currently ECC 6.00).

We already learned something about programs "RC1_REPORT_TO_ZIP" and "RC1_REPORT_TO_UNZIP", but this only seems to be usefull for already generated reports.

Thank you all in advance for your support!

Best regards,

Christoph

Hi Christoph

Before starting the WWI Compression, here are some basic settings need to take in consideration.

1) License Key Requirement:

As of version ERP 2004, the compression function is contained in the standard deliv-ery of EH&S WWI. You require a special WWI license key in order to use this en-hancement. When you upgrade from an earlier release to ERP 2004 or ERP 2005, you must request this license key.

2) Activation of WWI Compression Functionality:

To activate the compression use following entry in section [Global] of WWI.INI:

COMPRESSRESULT=1

Furthermore, the values listed below must exist in WWI.INI:

[COMPRESSRTF]

CHECKTEXT={\rtf

CHECKSTART=0

[COMPRESSDOC]

CHECKDATA=D0 CF 11 E0 A1 B1 1A E1 // Typical beginning of MS Word Documents

CHECKSTART=0

[COMPRESSZIP]

CHECKDATA=1F 8B 08 // Typical beginning of GNU ZIP Format

CHECKSTART=0

[COMPRESSWWI]

// () is a conjunction (AND)

// [] is a disjunction (OR)

// ! causes that zipped documents won't be compressed again

// Following checks if processed file is a RTF, DOC or ZIP and prevents zipping of already zipped files...

CHECKTYPES=([COMPRESSRTF COMPRESSDOC] !COMPRESSZIP) // Com-ments like this are allowed

Please See SAP Note 1300393 for further information.
