During the migration, the system can group together the contractsbelonging to a collective lease-out into one contract with thecorresponding number of rental objects. However, this does not happen ifyou did not enter the number of contracts to be grouped together inCustomizing for the migration under Make BasicSettings for Migration.
This message then appears only if the system finds a larger number ofindividual contracts during the conversion of collective lease-outs.
Keep in mind that contracts that are too large (that is, contracts withmany objects and/or conditions) can reduce performance.
For more information on contracts and performance, see SAP note 915080.
Grouping contracts is not mandatory. Therefore you can also ignore thismessage, if appropriate.
