[LSO] Resource types blocking

Question

Hi,
We have implemented SAP LSO at a customer, but during a training course we gave to the client, we came across the following problem:
When we are creating a course type and open the screen for attaching resource types (we have created multiple R objects) while someone else is executing the same action, SAP says the resource type is blocked by the other user (who first opened the selection screen).
We think this is quite strange since we are not actually changing the R object, just creating a relation with the course type (object D)
This is a problem since a large population will use LSO and probably create course types at the same time.
Is there a way to solve this problem ?
Thanks

A Workaround will be create the relationship Event type-Resource type after the Event type is created. You can do this by PP01 tx.
An example of this: centralize the creation of the relationship Event type-Resource type in one User (let's to say yourself).
Well, when anyone creates an Event type that requires a Resource type, he/she will send the requirement to you, and save the Event type without this assignment.
Then, in certain moment, you take the list of D objects that requires a specific Resource type, and:
1. go to PSVR transaction
2. select R object > right click > change
3. (you'll go to PP01 transaction) select the Relationships infotype and create the B022 relationship for each Event type.
Also, you can build a custom program that do something simmilar in order to automate the process.
Alsomore, i'm thinking another workaround:
You can change the relationship behaviour, in order to create only the "A" link when you create an Event type (that avoid to lock the resource), and then by using a program that run let's to say once a day, check every A022 relationships without the "B" link and then add the corresponding B022 relationship in R objects.
But i think meanwhile the "B" link is not done, many reports can bring erroneus or bad information.
