Sequence ID repeated

[Former Member]

Hi all,

We have an interface in serialization mode. We were sending messages each minute during 1 hour and we noticed that some sequence IDs were repeated. Also we saw that sequence ID values were between xxxxxx0000 and xxxxxx0099

is there any way to avoid that sequence Id be repeated?

is there any place where we can set up the range of values for that sequence ID?

Thanks for your help

Ivan

Hi Ivan,

Sequence ID has 10 digits and you are sending 60 messages/hour. As number of digits are limited to 10, in whatever manner you try to set the range of series or its starting value , the system will generate sequence ID equal to some previous values at some point of time or the other. In case you are utilizing the sequence ID in mapping then you can write an ABAP code to generate your own sequence ID. You need to do RFC to get a new value each time your scenario runs. Also in a table you can store last generated value, to ensure same number is not generated in the next instance. As you increase the number of digits to say 20 ,you can avoid the problem of repeatation for a longer time.

I believe it is PI internal and we might not able to alter the configuration that generates sequence/message ID.
