It has been learnt that CSA has been unable to procure a good broadcast deal as well as lucrative title sponsorship to set the ball rolling.
Matters have come to a head in recent days‚ with franchise owners unconvinced at CSA's ability to put the tournament together in a few weeks without those key elements.
The SA Cricketers' Association (Saca) has called on Cricket South Africa to establish an independent review into the decision to postpone the T20 Global League, and that players may seek compensation as a result.
"Having discussed it with Mr. Moroe and (CSA president) Mr. (Chris) Nenzani‚ we have arrived at a unanimous decision to defer the inaugural edition to next year‚" the release quoted a minority owner of the Pretoria Mavericks‚ Osman Osman‚ as saying.
Interim CSA CEO Thabang Moroe says a re-assessment of their strategy dictated that postponing the competition is the best option.
The postponement will create a six-week gap in the South African cricket calendar with no global or domesic cricket on the schedule from 3 November until 12 December.
Tony Irish, chief executive of the South African Cricketers Association, said the postponement would have "a very significant impact" on 144 local and overseas players who had signed contracts or been drafted to play in the eight-team league.
Mitchell McClenaghan had signed to play for the Durban Qalanders in the T20 Global League. "At this stage we're unsure of exactly what a postponement means other than the fact that it's clear the league will not take place this year".
"The players have contracts - about 140-odd are affected - and we maintain that they need to be compensated".
In addition to his IPL deal with Mumbai Indians, McClenaghan played for the St Lucia Stars in the Caribbean Premier League and has a contract with the Sydney Thunder in the Big Bash League.
"SACA is well aware of the fact that this will also affect various other groups including franchises, coaches and stadium owners", said Irish.
