• Message text: Value &1 invalid to be used in Secure Store ABAP

What causes this issue?

The Secure Storage ABAP can store character data with limit length only.
The length depends on the type of characters that are stored.
A minimum length of 36 characters can be guaranteed in all cases. If the
payload consists of characters in the ASCII 7-bit character set only,
109 characters can be stored. If the payload is a mixture of ASCII 7-bit
and other characters, the effective length can be somewhere between 36
and 109 characters.
The technical reason for this unpredictability is the usage of UTF-8 as
internal encoding which represents a character by a sequence of 1 to 3
bytes (depending on the character type). While ASCII 7-bit characters
are represented by 1 byte, Japanese characters have 3 bytes and German
Umlauts are in the middle with 2 bytes.

System Response

The provided value to be stored in the Secure Store ABAP is longer than
possible. The value can't be stored completely so the whole value is
rejected from Secure Store ABAP persistence.

How to fix this error?

Reduce the length of the content you want to store in the Secure Store
ABAP corresponding to the character set you use.
