Solution

[2.] Question: What is the length restriction in the SAP Data dictionary?

Answer:

SAP supports all standard hardware and software platforms for its products. With the database systems supported by SAP, there are different length restrictions for tables. With the restriction to 1962 bytes, the possible use of a two byte solution is already taken into account so that an increase of the value to 4000 bytes is in fact possible in almost all environments.

Unicode is enabled with SAP Basis 6.20. However, the required minimum release of the database platforms support a larger table width, so that that restriction was extebded ti 4030 characters with Basis Release 6.20. The enhancement is contained in Support Package 25.

As a result, the restriction of 1962 characters in lower releases is no longer valid. It can be extended to 4000 characters. We recommend that you do not extend it any further than this.

See note 636217.

For detailed information, see note 355898 (Restrictions for transparent tables) and note 636217 (DDIC activation errors due to table widths less than 1962 bytes).
