Process LOADING has no predecessor in Process chain

Question

Hi Experts,
I have copied Process chain with all process and I have included new steps in process chain like change log deletion  and delete & create index(the process chain has data mart functionality which mean that, first it load to DSO and then from DSO it load to Cube) so after Start variant I have included Change log deletion Step and then after Activation of DSO I have included delete Index step and then after IP load to Cube I have included Create Index step therefore which is the PC in the form of
1) Start Process
2) Change log deletion
3) Load IP (Target to only PSA)
4) Read PSA and Update to data target (DSO)
5) Activate the DSO
6) Delete Index
7) Load IP (Data mart from DSO to Cube)
8) Create Index
9) Delete request from PSA.
all process are connected but when I activated I was getting error message that Process LOADING has no predecessor
so pls advise me what went wrong or what should I do.
Note
1) load type is full load and I was in BI.7
2) there is no DTP engaged

Hi
during creation of modification of chain you must have deleted few links to Loading step.
Go to settings-> Default chains  and see if autosuggest is on, if it is on this might have cause this.
To Resolve this problem go to edit mode of chain and then go to View->Detail view on
now you will be able to see unlinked loading step.
Delete unlinked and un necessary steps from here and reactivate chain.
Hope this works
